How to customize lithium-ion batteries?

Lithium-ion batteries are almost everywhere around us. These are the current golden standard for rechargeable battery applications since they find their usage in most consumer electronics, gadgets, etc. These batteries are available in specific options and if more power is required, those already available options are used in a series, parallel, or mixed connection.

However, for some use cases and projects, it is more efficient to customize a lithium-ion battery tailored to the requirements. So, in this article, we will discuss all the important factors for customizing your lithium-ion batteries.

Product Design

The first part of customizing your lithium-ion batteries is about the product design, where you design the shape and size of your battery. You also get to pick the right materials for every component and ensure by research that the battery will operate safely.

Customizing the Shape and Size of the Battery

You may have noticed that different devices use lithium-ion batteries of different shapes. Some have cylindrical cells, while others, like smartphones and other gadgets, have square-rectangular flat batteries. You can get your batteries produced with your shape and size pacifications, and in most cases, it goes according to the project in which that battery will be used. With this customization, you can work on the aesthetic appeal of the battery and the whole project if performance and safety are maintained.

Selecting the Right Materials for Every Battery Component

The next thing you want to customize is the interior. It contains multiple components, including:

Cathode

Anode

Electrolyte, etc.

Since you are customizing your battery, you have control over which materials you want to pick. Some materials may not be perfect for your use case or battery size, while some might be efficient. Here are some basic qualities that you must look for in battery materials:

Electrodes: energy density, discharge characteristics, and thermal stability.

Electrolyte: battery composition design, performance characteristics with electrode material.

Working on the Safety and Reliability of the Battery

Before finalizing any of these, there is one step left in product design, and that’s about safety and reliable performance. Remember that heat is a big enemy of lithium-ion batteries. Similarly, if the battery is too easy to puncture in your project or it accidentally gets punctured, that may start a fire. In addition, thermals work on charge protection as well.

Battery Weight

Now that you have worked on the design section, we will move to the battery weight section since it has a lot of importance in most applications these days. For example, smartphones and laptops are becoming lighter and lighter every day. So, your battery design cannot be too heavy in that case.

The Importance of Balancing the Weight and Capacity of the Battery

It is important to maintain a balance between the weight and capacity of the battery. An efficient design comes with a balanced capacity regarding its weight. It is vital for improving the overall efficiency of the application where every gram matters. Additionally, it can improve the overall safety of your battery since the battery will not be overburdened.

Benefits of Picking Lightweight Electrode Materials

When you pick lightweight electrode materials while customizing your battery, here are the top benefits you can enjoy:

A significant drop in weight and improved energy density

Better weight-performance ratio

Improved cycle life

Possible robust power delivery

Improved thermal stability and more.

Managing Weight by using Energy-Dense Materials and Reducing Casing Weight

A major part of the overall battery weight comes from the electrodes. You can change that by picking the right electrode materials. It is a better option to pick materials that bring better features like:

Improve thermal stability

Better cycle life

Safer operation

Les weight

In this way, the performance of lithium-ion batteries will be maintained or improved. Meanwhile, these factors will help you reduce some grams of the total weight of your battery. Additionally, opting for other feasible materials for casing might help.

Battery Performance

The last thing to customize is battery performance, and it can be the most important of all, depending on the use case. For example, some applications want the battery to last long, while some want a sudden burst of power. Here is everything you must know when customizing battery performance:

Improving the Energy Density of the Battery

Improving the energy density of your battery means that you are getting a better volume-capacity ratio from your battery. Improving it means that the cycle life and overall lifespan of your battery will improve. This quality is of huge importance in electric vehicles and electric cordless tools. It can be improved efficiently by the right product design approaches.

Improving Cycle Life to Prolong the Battery's Lifespan

Next, we need to ensure that the cycle life is improved further, which will improve the lifespan of your battery. It also means that you can get a stable performance with reliability from the same battery for a long time. Optimizing your electrolyte materials can help along with working on charge-discharge cycles of the battery

Working on Thermals to Ensure Safety and Stability

The last thing you must work on regarding battery performance is its thermals. You need to work on thermals while charging and during use. Managing thermal stability by means of efficient designing or using external cooling solutions can help a lot. It not only keeps the performance stable with continuous usage but also improves the long-term safety of the battery.

If the battery is used in extreme hot or cold conditions, it is better to use thermal insulators to protect battery internals from the harshness of external weather.

Conclusion

Lithium-ion batteries are already available in multiple cylindrical and flat design configurations with varying specifications. However, if your use case is not satisfied by the already available options and using mixed connection battery packs is not efficient, then you can customize these batteries. Before you customize the lithium-ion batteries for your project, it is important to conduct thorough research.

You must have information about the design and working of these batteries and how you will customize one to meet your requirements. So, whenever you customize a lithium-ion battery, keep all the factors discussed in this article in mind for better results.
